Benign essential tremor can be distinguished from parkinsonism by its rapid frequency, the involvement of voice and head, and the common finding of a positive family history. Essential tremor is less incapacitating than parkinsonism and less inexorably progressive. Propranolol (Inderal) is the best therapy available at this time. The transient beneficial effect of alcohol is deceptive. Patients with this disorder, although they find the tremor embarrassing, are generally not incapacitated and are otherwise in excellent health.
良性特发性震颤可通过其快速的频率、累及声音和头部以及常见的阳性家族史与帕金森病相鉴别。特发性震颤比帕金森病致残性更低，进展也不那么不可阻挡。普萘洛尔（心得安）是目前可用的最佳治疗方法。酒精的短暂有益作用具有欺骗性。患有这种疾病的患者，尽管他们觉得震颤令人尴尬，但通常不会致残，而且在其他方面健康状况良好。
